Mixed Gases for Welding

Sure-Shield

Maintaining gas mixture integrity with high-pressure cylinders is the key to achieving high-quality welding. That’s why we developed our “SureShield” mixing system for two-, three- and four-part argon-based blends containing carbon dioxide. It provides industry-leading mixture consistency from cylinder to cylinder, from start to finish, which:

  • Lowers residual cylinder losses
  • Ends premature cylinder change outs
  • Helps eliminate costly rework

Carbon Dioxide

Carbon Dioxide (CO2) is used as a welding gas, a beverage gas, a refrigeration gas and as a blanketing gas for chemical reactions and other applications requiring a chemically inert gas. The Bone Dry and Anaerobic Grades of Carbon Dioxide are used as atmospheres for anaerobic incubation in microbiology labs. Coleman Instrument Grade is a carrier gas for the Coleman Oxygen Analyzer. Medical carbon dioxide is used for various medical purposes, such as in its liquid phase, where it provides sub-zero temperatures for cryo-therapy or other surgical practices.

The family of companies that comprise Phoenix Welding Supply provide Carbon Dioxide (CO2) to business groups from beverage, welding, instrument & medical and for liquid industrial freezing applications statewide.

Acetylene

Acetylene Gas – a colorless, flammable gas with a garlic-like odor. Acetylene has the highest flame temperature of any common hydrocarbon because of its triple-bond structure H-C=C-H. Combustion with oxygen achieves a flame temperature of 5580° F (3087° C), releasing 1470 BTUs per cubic foot. Its high flame temperature allows it to be used in a variety of metal working applications like cutting, welding, brazing, and soldering.

We are the largest manufacturer of Acetylene Gas in the Southwest. Contact Phoenix Welding Supply Co. for more details.

Bulk Gas

Bulk Liquid Delivery Systems – For many users the bulk liquid delivery system is the preferred source for liquid argon, carbon dioxide, hydrogen, nitrogen, oxygen and semiconductor process gases in a full range of purities. These high-purity gases are transported from our contracted production plants to storage tanks at customer sites. A variety of tank sizes is available to suit individual customer needs.

Before any recommendations are made, our local experts will work closely with your team to determine the optimum system for the bulk supply of gases required, purity level, flow rate, pressure, usage pattern and site location that best meets your needs. Praxair also offers temporary installations and special services to help maintain product flow during system change outs or upgrades.

We utilize a remote monitoring system that manages your cryogenic inventory, automatically placing refill orders and ensuring reliable supply. We have monitoring ability for the following products:

  • Bulk Liquid Nitrogen, Oxygen and Argon
  • Bulk Gaseous Helium: Tube Trailer & ISO
  • Bulk Semiconductor Process Gases

Helium

Helium is a unique, multipurpose molecule—but it is a finite resource as a mined gas. Global demand for helium is growing annually at an unbelievable rate. Helium is a critical element in many industrial, medical and research laboratory applications. We understand your need for a reliable and worry-free supply. As the valley’s major supplier of gaseous helium (via traditional cylinder & tube trailer delivery systems), Phoenix Welding Supply Company is in a unique position to provide helium customers with a secure, reliable supply, along with expert applications support.

With multiple long term procurement contracts in place, Phoenix Welding Supply Company is in the enviable position to say that it has NEVER allowed a customer to be in a situation to be out of product. To date, no other Arizona company can lay claim to this undeniable fact.

Oxygen

Oxygen (O2) constitutes approximately 21% of the air, has a gaseous specific gravity of 1.1, and has a boiling point of -297.3°F (-183°C). Oxygen is produced by air separation processes that use either cryogenic liquefaction and distillation or vacuum swing adsorption (VSA) separation. Oxygen can be stored and shipped as either a gas or a cryogenic liquid.

The principal uses of oxygen stem from its strong oxidizing and life-sustaining properties. It is used in medicine for therapeutic purposes and in the metals industry for steel making and metal-cutting applications. In the chemical and petroleum industries, oxygen is used in the production of a wide variety of fuels and chemicals. Oxygen is used in the pulp and paper industry for a variety of applications, including pulp bleaching, black liquor oxidation, and lime kiln enrichment. In the glass industry, oxygen/fuel combustion is used to reduce particulate and NO x emissions in melting operations. Oxygen is also used for gasification applications for producing synthesis gas to make chemicals, fuels, electricity, hydrogen or steam.

Nitrogen

Nitrogen (N2) constitutes 78.03% of the air, has a gaseous specific gravity of 0.967, and has a boiling point of -320.5°F (-195.8°C) at atmospheric pressure. It is colorless, odorless, and tasteless. Nitrogen is often used as an “inert” gas due to its non-reactive nature with many materials. However, nitrogen can form certain compounds under the influence of chemicals, catalysts, or high temperature. Commercial nitrogen is produced by a variety of air separation processes, including cryogenic liquefaction and distillation, pressure swing adsorption (PSA), and membrane separation.

Gaseous nitrogen is used in the chemical and petroleum industries for storage tank blanketing and vessel inerting applications. It is also used extensively by the electronics and metals industries for its inert properties. Liquid nitrogen, produced by the cryogenic air separation process, finds wide use as a refrigerant in applications such as cryogenic grinding of plastics and food freezing. It is also widely used in the medical field.

Argon

Argon (Ar) is a monatomic, chemically inert gas composing slightly less than 1% of the air. Its gaseous specific gravity is 1.38 and its boiling point is –302.6°F (–185.9°C). Argon is colorless, odorless, tasteless, non-corrosive, nonflammable, and nontoxic. Commercial argon is the product of cryogenic air separation, where liquefaction and distillation processes are used to produce a low-purity “crude” argon product which is then purified to the commercial product.

Argon is used primarily for its properties as an inert gas in applications such as arc welding, steel making, heat treating, and electronics manufacturing.
